Overview
Brief Summary
Knee osteoarthritis has a very high prevalence in the population over 50 years of age. Patients with osteoarthritis often suffer from chronic pain that becomes disabling, affecting both quality of life and mental and physical health. This pathology has also been linked to maladaptive plasticity in the brain, which can contribute to chronic pain. Therapies with neuromodulatory approaches, such as transcranial direct current stimulation (tDCS) and peripheral electrical stimulation (TENS), have been used therapeutically to counteract the maladaptive plasticity of the brain.
Transcranial therapy and TENS can be a possible effective treatment in the rehabilitation services of the health system for the improvement of chronic pain and quality of life in different pathologies, such as chronic low back pain, fibromyalgia or knee and hip osteoarthritis.

Outcomes
Primary Outcomes
Chronic Knee Pain
Time Frame: Through study completion, an average of 1 year.
The Visual Analogic Scale will be used to assess the impact on chronic knee pain. The values range from 0 to 10 (0 = No pain, 10 = the worst pain).
Secondary Outcomes
- Coordination and Balance(Through study completion, an average of 1 year.)
- Function and Quality of Life(Through study completion, an average of 1 year.)
- Force(Through study completion, an average of 1 year.)
- Balance(Through study completion, an average of 1 year.)
- Gait properties.(Through study completion, an average of 1 year.)
- Central Sensitization(Through study completion, an average of 1 year.)
- Kinesiophobia(Through study completion, an average of 1 year.)
- Uncertainly(Through study completion, an average of 1 year.)
- Catastrophizing(Through study completion, an average of 1 year.)
